Gisele Bundchen isn’t the only sore loser left cursing after the New England Patriots’ crushing loss at the hands of the Giants.

Connor Cruise — a die-hard Patriots fan and the DJ son of Tom Cruise — lashed out at one of his reps, Todd Krim, who tweeted after the game, “Sorry @TheConnorCruise maybe next year!!!”

According to an e-mail forwarded to publicists by Krim, Cruise, 17, texted him back, saying, “That was a gay ass [bleeping] tweet . . . U don’t say [bleep] like that about my team the second they lose. Low.”

Cruise and Krim were both in Indy where Cruise DJed DirecTV’s Saturday night party. Krim says the Twitter tantrum ended their professional relations, while sources close to Cruise say they’d parted ways weeks ago.

On Monday, Krim e-mailed colleagues with a screen grab of Cruise’s texts, saying, 😉“I am no longer working with Connor Cruise. In fact, I am no longer speaking with [him] . . . I refuse to be professionally (or even personally) associated with someone that engages in this sort of behavior . . . I just thought you should know who and what you’re dealing with.”

He called Cruise’s comments, “highly offensive and what I consider homophobic . . . after I jokingly tweeted about the Patriots losing.”

Krim told us, “I did a lot for [Connor], and he was less than respectful and appreciative . . . I made a joke, and let’s just say his reaction was not what I expected. It’s disappointing when you think someone is one way and they turn out to be another.”

Cruise told Page Six through his rep: “What I texted was unacceptable. It is not a reflection of who I am and what I feel, and it certainly won’t happen again.”
